The interface is very simple, easy to use in comparison to other products I've used before.
A couple of questions were answered incorrectly during my trial period but this was quickly rectified by customer support within minutes! Customer service from start to finish has been nothing short of amazing - they are always open to feedback/suggestions so it's impossible not be pleased here. No complaints at all really - great product that does exactly as advertised without any issues. Centralising our knowledge base across departments and making information easily available when needed.
